They can range in size from just a few inches tall to more than 12 feet in the case of the tree ferns. Some types of ferns are tropical. Others quite hardy. Their versatility aside, ferns are valuable in the home and garden because they prefer shade. In the landscape, ferns bring fresh green life to those hard-to-design dim corners.
Prokaryotic cells have various shapes; the four basic shapes are: Cocci - spherical Bacilli - rod shaped Spirochaete - spiral shaped Vibrio - comma shaped.
The cytoplasm in prokaryotic cells is a gel-like, yet fluid, substance in which all of the other cellular components are suspended. Jello for cells. It is very similar to the eukaryotic cytoplasm, except that it does not contain organelles.Recently, biologists have discovered that prokaryotic cells have a complex and functional cytoskeleton similar to that seen in eukaryotic cells.ecause prokaryotic cells, by definition, do not have a nucleus, the single large circular strand of DNA containing most of the genes needed for cell growth, survival, and reproduction is found in the cytoplasm.
